' TYPE-BAR.

Application filed September 21, 1915. Serial No. 51,750.

To all whom it may concern Be it known' that I, OLIVER PERRY ANDER- SON,a citizen of the United States, residing at Nashville, in the county ofDavidson and State of Tennessee, have invented certain new and usefulImprovements in Type-Bars;

and I do hereby declare the following to be a full, clear, and exactdescription of the mvention, such as will enable others skilled in theart to which it appertains to make and use the same. v

This invention relates to type bars and is more particularly adapted fortypewriting machines.

One of the objects of this invention is the production of a type barprovided with atmeans whereby the type may be readily character of. the

- changed, or in case of damage to the type the same may be readilyreplaced. 0

Another object of this invention is the for efficiently retaining andlocking the type upon the type bar.

Other objects and advantages of this invention will be hereinafter moreclearly set forth in the specification, defined in the claims, andillustrated in the accompanying with the head. 8

ings, 1 denotes the type 4 upon the drawings, in which,

.Figure 1 is a side view of the device. Fig. 2 isan end view of thedevice shown in Fig. 1. Fig. 3 is a side view, partly in section,showing one means for. mounting the type upon the type bar. Fig. 4 is aside View, partly in section, showing another means for mounting thetype upon the type bar. Fig. 5 is an. end view of the device shown inFig. 4.

Referring to Figs. 1, 2, and 3 of the drawthe aperture 2 adjacent one ofits ends, one end of the aperture being formed with the countersinkMounted upon the typebar 1 is the type block 4, formed with the shank 5,provided with the reduce'd end or stem 6 and the shoulder 7, the stem (3passing through the aperture 2 of the bar 1 with the shoulder 7 bearingagainst one face of the t pe bar 1, and the end of the stem (5 formedwithin the countersink 3 of 2, thus securing the type block type bar 1.The type bar 1, the shank 5'. and the face of the type block 4 aresubstantially the same width, but the type block 4 is elongated" in thelongitudinal dithe aperture rection of the type bar 1. The type block 4block bar, provided with Specification of Letters Patent.

.which type may shank 26. the sleeve Patented Jin 4, 1916. P

is provided with the flat face 9, the downwardly and inwardly inclinedsidewall 10, and the straight wall 11 formed with the inwardly directedundercut portion 12. The type block 4 is also provided in its face 9with the recess 13 as shown in Fig. 3. For supporting thetype upon thetype block 4, a metal support, preferably formed of a flat plate ofspring brass, is provided. This 1 supportis bent to provide the baseplat 14 upon which is secured the type 15 and 16,

be the small letters and capital letters. The plate or support for thetype is bent to provide the downwardly and inwardly inclined springmember 17 for en gaging the side wall 10 of the type block 4, and thesupport for the type is further bent. with the downwardly extendingspring mem- 4 ber 18 for engaging the side wall 11 of the type block 4,the lower edge of, the spring member 18 being inwardly-bent to providethe gripping end 19 for engaging-the undercut portion 12 of the typeblock 4. Upon the under side of the base 14 of the type support isformed the lug 20 for engaging the recess 13 in the face .of the typeblock 4.

In Figs. 4 and 5, 21 denotes the type bar provided with the recess 22formed at a point slightly remote from the end of the bar. Mounted uponthe. end of the bar 21 35- is the type block 23 having formed upon itsface the type .24 and 25, which type may be the usual small letters andcapital letters. The type bloct 43 is provided with the shank 26, uponthe lower end of which is provided the elongated ferrule or sleeve 27.The ferrule or sleeve 27 is disposed transversely or right angularly tothe shank '26, and has its closed end '28 projecting slightly beyond:one side of the shank 26. while the open end 29 of the sleeve 27extends for a greaterdistance beyond the other side of the 27 beingprovided with the lug 30, adjacent its open end 29. for en'- gaging therecess 2; of the type bar 21.

In the type bar shown in Figs. 1. 2, and 3, the base plate or support 14may he a plate having one character of type thereon. and should it 'bedesired to substitute this plate with another having a differentcharacter of type. the first plate may be readily removed by grippingthe type supporting plate with the fingers. or a suitable tool. andforcing the same lengthwise of the type 4.. This movement will cause thelug 110 of the of the 1 spring members of the second type plateimpinging the side, walls-1O and 11 of the block 4, and the lug upon thesecond plate engaging the aperture 13 for locking the second plate upon.the type block 4, the second type plate having upon its face, of

I course, type of'a different character.

By forming the side wall 10 of the block 4 and thespring member 17 ofthetype grasping the sleeve 27 with .plate 14 of one shape,

and the sidewall 11 of the block 4and thespring member 11 of they typeplate 14 of another shape, provides an efficient means for preventingthe sub-- stituted type plate from being wrongly positioned upon thetype block 4. If it is not desired to change the character of the type,this arrangement is equally efficient, of course, for substitutinganother plate of similar type for the one previously used,

should the type on this latter plate become I damaged from any cause orreducing the cost ofrepairs. I In the .type bar shown in Fig worn out,thus s. 4 and 5,

. the type may be readily substituted by other type for either changingthe character of the type when desired, or for replacing the type withother type when the first type has become damaged or injured in any way,by the fingers, or a suitable tool, and forcing the sleeve out- -wardly,which movement will release the locking lug 30 from its engagement withthe recess 22 of the type bar 21, whereby the present type block 23 withits type thereon is removed, and a substituted type block introducedupon the end of the type bar 21.

\Vhile I have here shown and described the preferred.embodiment of theinvention, minor variations I and alterations may be :made therein fromtime to time without departing from the spirit of the invention or thescope of the claims. Having described my invention, what I claim as newand desireto secure by Letters- Patent, is

1. In a combination with a type; bar, of means to provide for theinterchanging of the type upon the bar, means to render impossible thepositioning of the type in inverse order upon the type bar at any stage,and means for locking said type upon said bar, said locking meanscomprising a recess and a lug for locking engagement with the recess.

2. In a device of the class described, the combination with a type bar,of a type block secured upon said type' bar, said type block having aflat face and its side Walls disposed at different angular relations toits face, a type plate having depending resilient members of the contourof the side Walls of said block for embracing the same, and means fordetachably securing said type said type block. I I 3. In a device of theclass described, the combination with a type bar, of a type blocksecured upon said bar, said type block having a fiat face provided Witha centrally disposed recess therein, one of the side walls of said typeblock being acutely undercut, the

device of the class described, the

plate upon other of the side walls of the type block being disposed inright angular relation to the face of said block but having its lowerportion acutely undercut, a type plate for said adapted to seat in therecess of said type block'for detachably securing said type plate uponsaid type block, said type plate having depending resilient sidemembers, one of which is formed to snugly engage the acutely type blockhaving a centrally disposed lug undercut side wall of said type block,the

other formed to snugly engage the right angular-1y disposed side wall ofsaid type block and having its lower edge inwardly bent forengaging thelower undercut portion of said side wall, whereby to render impossiblethe positioning of said type plate upon said type block at any stagewith the type in inverse order.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
